The process consists in reacting an oxygenic transition metal compound such as 99m Tc , 186 Re or 188 Re , with a first nitrogenous ligand such as sodium nitride or a nitrogenous compound such as S-methyl, N-methyl dithiocarbazate, and a reducing agent consisting of either tin (II) or a dithionite. The product so obtained can be used for the preparation of radiopharmaceutical products by a reaction with a second ligand such as sodium dithiocarbamate.
